Abstract
Accurate modeling of electromagnetic wave propagation by means of ray tracing (RT) includes not only specular reflection, penetration through dielectric blocks and diffraction, but also diffuse scattering mechanisms. The accuracy, supported by a precise description of the environment, is achieved at a very high computational complexity. This computational complexity scales directly with the number of propagation paths, of which the diffuse scattering paths comprise a large proportion. In this paper, we propose a general subdivision algorithm for diffuse scattering of RT in indoor scenarios based on concentric circles. The proper tile size is defined according to the system bandwidth. The method significantly reduces the computational... (More)

In this paper, we propose a general subdivision algorithm for diffuse scattering of RT in indoor scenarios based on concentric circles. The proper tile size is defined according to the system bandwidth. The method significantly reduces the computational complexity of RT with no loss in accuracy. The method is verified by evaluating the power delay profile (PDP), delay spread and angular spread. (Less)
